Abstract

This study identified the effect of girdling and different concen­trations of growth regulators on fruit drop, of trees persimmon (Diospyros kaki L). GA3 at 20p.p.m. plus girdling at full bloom decreased fruit drop and consequently increased the yield. The girdling treatment only during full bloom significantly increased final yield, while, treatment of growth regulators spraying plus girdling gave the best yield compared with the yield of control trees. The treatment of GA3 plus girdling tend­ed to give larger leaf area and leaf dry weight, while girdling treatment gave small leaf area. Girdling treatment at full bloom increased leaf and shoot total carbohydrate compared with control. Girdling significantly improved fruit weight and size while, total soluble solids (T.S.S) level was slightly affected by girdling for applied treatment. There was insignificant effect on acidity and fruit colour of persimmon.
